Can't unroot using petes tool

I have a droid 3 and i have been trying to unroot using petes unroot tools. I am new to rooting, pretty much did it to take screen shots. It keeps saying that I need to create a subfolder \restore\ . I have downloaded the links he provides for a restore but it never gives me the option to browse for the files in which to use. I have created folders on my desktop and made subfolder with proper name but no luck.. any help would go along way as I haven't received any of the ota updates. Thanks again for any help.

That makes one of us..lol.. I have heard horror stories of bricked phones and whatnot... I will look into it tonight when I get off work. Ill. Keep you updated..(unlike my phone...lol).. thanks a million! !

Oh ya, did you delete any of the apps that came on phone? If you didn't, it's just asking you if you want to restore those, if you don't need to, just say no. But if you do need to, if i remember correctly (sorry, it's been awhile since I last unrooted) you just need to make a folder named restore and download the app data (i believe pete's tool gives you a link) and put it in the folder and then just put the folder into the same folder as the pete's tool exe.
